Solid build, quality materials but read the manufacturer's warning (which I didn't do pre-purchase). I have a MacBook Pro 13 inch 2017 with Touch Bar (4 Thunderbolt ports) and plugging the hub into a port on the left side disconnects my WiFi connection. The warning provides tips for how to prevent this (changing WiFi to 5GHz band) but instead I plug it in to one of the ports on the right of my MBP. Update (September 2019): still no issues transferring data with this hub. 4 star rating still applies.
